SNOW-MELTER FOR RAlLROAD- SWlTCHES.

SPECIFICATION forming part of Letters Patent No. 690,742, dated January '7, 1902.

Application filed August 13,

To all whom it may concern:

Be it known that I, GEORG KOVAOS, a citizen of the United States, and a resident of Trenton, Mercer county, New Jersey, have invented certain new and useful Improvements in Snow-Melters forRailroad-Switches, of which the following is a specification.

This invention relates to an improved apparatus for rapidly melting the snow and ice around railway-switches, so that any obstruction to the free movement of the latter may be effectively avoided or removed.

In the accompanying drawings, Figure 1 is a plan of my improved snow-melter; Fig. 2, an enlarged section on line 2 2, Fig. 1; and Fig. 8, anenlarged section on line 8 3, Fig. 2.

The letters a, b, and 0 represent the trackrails, and d represents the sWi tch-rails. Along the switch-rails 01 extend a pair of parallel steam-tubes e ,e, perforated, as at c and connectedbymeansofatransversetubee Steam is admitted to the tube e from a suitable boiler (not shown) by means of a main steam-pipe f, that receives the steam at the upright pipe f and conveys it to tube e by an elbow From the tube a the steam flows into The outer branch tubes 1901. Serial No. 71,905- (No model.) I

it have upwardly-projecting nozzles h, while the inner branch tubes 2' have horizontal nozzles t" to direct the steam against ground ice. Within the space inclosed by the branches 1 there radiate from main pipe f a pair of branch pipes 70, having upwardly-turned nozzles it. The steam flowing through the pipes f 6 6 e and through the radiating branches 9 h t' It will melt the snow at the side of and around the switch, the area attacked increasing gradually from the pipe f toward the rails. Thus a surface sufficient for the free movement of the switch is cleared from snow and ice.

What I claim is- 1. A snow-melter for railway-switches composed of a steam-supply pipe, and a series of branch pipes radiating therefrom and having nozzles turned in difierent directions, substantially as specified.

2. A snow-m'elterfor railway-switches composed of a steam-supply pipe, a pair of radial pipes g, having branches h, '5, provided with nozzles 72., 'i, and a pair of branches is, having nozzles is, substantially as specified.

Signed by me at Trenton, Mercer county, New Jersey, this 3d day of August, 1901.

GEORG KOVAOS.
